An infrared camera is a device that captures images using infrared radiation, which is not visible to the human eye. These cameras detect heat emitted by objects, allowing them to create images based on temperature differences. They are commonly used in various fields, including building inspections, surveillance, and medical diagnostics. Infrared cameras can reveal details that standard cameras cannot, such as heat leaks in buildings or the presence of warm bodies in low-light conditions. They are valuable tools for firefighters to locate hotspots and for engineers to assess equipment performance by identifying overheating components.
